Other Fuel System Tank Filling/charging Problems of Subaru Impreza

The gas guage innaccurately describes how much gas is left in the tank. I filled my tank from 40 miles two weeks ago. I paid $32 for the gas and it only read 170 miles till empty unlike the usual 300 miles. 5 hours later, when it corrected itself, returning to 300 miles. This week, upon filling my car up at 40 miles till empty, I paid $28. My car read 280 miles till empty and then shot up to 300 miles half an hour later. I feel unsafe to let my car go long periods of time without filling with gas. I called my local Subaru dealership and they wanted me to wait almost 3 weeks to bring my car in, even when stated that I heard of this happening previously with other 2011-2016 Subaru Imprezas. Their response was less than comforting "claiming" they have had no prior knowledge or trends of this happening with my generation Impreza, only the newer model Imprezas and crosstreks.
